One spring day, Mole decides that he has had enough of the tiresome spring cleaning. He throws down his broom and hurries out of his underground home into the sunny world outside looking for adventures and new friends. He quickly finds both in the form of the Water Rat, who takes him boating and introduces him to life on the river and in the Wild Wood. Mole soon befriends the very kind Badger and the preposterous and boastful Toad. In time, the quartets' escapades—including car crashes, a sojourn in jail for Toad and his spectacular escape, and a battle with weasels and stoats to reclaim Toad Hall—become the talk of the inhabitants of the riverside.

The Wind in the Willows, Kenneth Grahame's classic tale, has attracted readers of every generation and the quartet continues to delight their readers with their odd adventures.
